Abstract Objective: To evaluate the applied value of CDFI in lateral circumflex femoral artery(LCFA) perforator flaps. Methods: Thirty-two patients were treated by our hospital from Jan. 2015 to Nov. 2016, perforating branches of LCFA were examined in 32 patients using CDFI. The following parameters were detected: jumping-off point, number, diameter(≥0．5 mm)，course, location and peak blood velocity, and they were marked on patients’ body surface. The perforator with wider caliber, faster flow speed, and shorter intramuscular trajectory was selected, and the flap was designed according to the observed results. Results: Thirty-two trunk arteries and 72 perforating arteries were examined and 69 confirmed by operation with an accuracy rate of 95.8%. The inner diameter ranged from 0.5 mm to 1.5 mm. Thirty-two cases of patients, and among which 57 were myocutaneous perforator, 15 were septocutaneous perforator. Totally, 2 patients were detected by CDFI only 1 perforator in the flap area, 12 patients were detected 2, 16 patients were detected 3, and 2 patients were detected 3 or more. Conclusion: CDFI had much higher application value in designing perforator flap of LCFA before the operation.
